The 2015 Seattle GNU/Linux conference (SeaGL) call for proposals is now open. I've submitted a proposal for a 50-minute workshop regarding how to edit Wikipedia, and may submit more proposals in collaboration with my colleagues in Cascadia Wikimedians. I'm sure that SeaGL would be happy to consider technical presentations about MediaWiki, Wikimedia analytics, Wikimedia Labs, our upstream tools, etc. if you're interested. Please consider submitting a proposal and coming to Seattle for the conference.
Regards,
Pine
